急性梗阻性化脓性胆管炎(附121例分析)

本文对121例急性梗阻性化脓性胆管炎(AOSC)进行了临床分析讨论了诊断及治疗。结果表明,早期诊断,尽快手术治疗,积极防治并发症,是提高疗效降低死亡的关键。肝肾功能衰竭和中毒性休克是本病的主要死因,占死亡总人数的83％,60岁以上的老人不是手术的禁忌症。

Extracorporeal Septoplasty Combined with Open Rhinoplasty

Extracorporeal septoplasty is a radical solution for the severely deviated nose. The major problems associated with this procedure are fixation of the septal cartilage graft and dorsal irregularities. Extracorporeal septoplasty was performed in combination with open rhinoplasty in 17 patients with severe nasal deformities. In this technique septum was totally removed through the columellar incision of open rhinoplasty, corrected outside, and replaced as a free ``L' shaped cartilage graft. The cartilage graft was fixated to the upper lateral cartilages to restore the natural relations of the anatomical structures. Additional rhinoplastic manipulations were also performed. The follow-up period was up to 18 months. The overall result was successful in all patients. Nasal deviation did not recur and secondary revisions were not needed for any patient during follow-up.     

Sarcoidosis and primary biliary cirrhosis

Summary An unusual case of a woman with primary biliary cirrhosis and cutaneous sarcoidosis is described. The factors that allow a specific diagnosis of each condition are presented and the literature pertaining to such complex and unusual cases is presented.This work was supported in part by a grant from the Gastroenterology Medical Research Foundation of Southwestern Pennsylvania.     

十二指肠乳头括约肌切开胆总管取石术前静注咪唑安定对麻醉及手术效果的影响

目的　探讨在十二指肠乳头括约肌切开 (EST)胆总管取石术前静注咪唑安定的可行性及价值。方法　将 71例拟行 EST胆总管取石患者随机分为咪唑安定组 (试验组 ) 5 1例和对照组 (2 0例 ) ,两组术前均给予 6 5 4 -2 (10 mg)静脉注射 ,试验组同时静脉注射咪唑安定 (3～ 5 mg)。观察两组患者的进镜时间、麻醉程度 ,患者的反应与配合程度、自身感受程度 ,同时监测患者的血压、心率、血氧饱和度。结果　试验组进镜时间缩短、镇静程度适中、患者自身感受好 ,与对照组比较 ,差异有显著性 (P<0 .0 1) ;患者心血管及呼吸参数无明显变化。结论　EST胆总管取石术前静脉注射咪唑安定可提高麻醉效果 ,有利于提高患者配合的依从性 ,对血压、心率、血氧饱和度无明显影响     

Long-Term Outcome of Adult-to-Adult Living Donor Liver Transplantation for Post-Kasai Biliary Atresia

Our objective was to analyze problems in the perioperative management and long-term outcome of living donor liver transplantation (LDLT) for biliary atresia (BA). Many reports have described the effectiveness of liver transplantation (LT) for BA, particularly in pediatric cases, but little information is available regarding LT in adults (> or =16 years old). Between June 1990 and December 2004, 464 patients with BA underwent LDLT at Kyoto University Hospital, of whom 47 (10.1%) were older than 16 years. In this study, we compared the outcomes between adult (> or =16 years old) and pediatric (<16 years old) patients. The incidence of post-transplant intestinal perforation, intra-abdominal bleeding necessitating repeat laparotomy and biliary leakage was significantly higher (p < 0.0001, <0.001 and <0.001, respectively) in adults. Overall cumulative 1-, 5- and 10-year survival rates in pediatric patients were significantly higher (p < 0.005) than in adults. Two independent prognostic determinants of survival were identified: a MELD score over 20 and post-transplant complications requiring repeat laparotomy. Outcome of LDLT in adult BA patients was poorer than in pediatric patients. It seems likely that LT will be the radical treatment of choice for BA and that LDLT should be considered proactively at the earliest possible stage.     

Nasal nicotine spray: a rapid nicotine delivery system

Plasma nicotine concentrations following administration by two types of nasal nicotine spray were compared in ten subjects. Absorption was particularly rapid during the first 2.5 min, the average rise in blood nicotine concentrations during this time being 8.6 ng/ml for the two products, followed by a small further rise to an average peak increase of 10.5 ng/ml 5 min after the dose of 2 mg nicotine base (mean 27.8 micrograms/kg). Despite a four-fold Cmax variation between subjects, the levels of individual subjects were fairly consistent across the two products. There were no significant differences between the two products in blood nicotine concentrations or cardiovascular responses, and the correlation between the AUCs from the two products was 0.68 (P = 0.01). Eight subjects reported subjective feelings of light-headedness or slight dizziness, which are not typical after slower absorption from nicotine gum or skin patches. Blood nicotine levels within the smoking range were soon built up with repeated doses, even in the subject with the least efficient nasal absorption. In a second study of ad libitum use under clinical conditions both products appeared sufficiently acceptable for therapeutic use as an aid to smoking cessation. There was no tendency to escalate to excessive use over 4 weeks, and blood nicotine concentrations in nine subjects averaged only 44% of their prior smoking levels. Only one subject had levels equivalent to prior smoking and possible reasons why this was not more common are discussed.     

动物与临床胆道梗阻和胆道炎症时胆管组织PGI_2和TXB_2的变化

采用放射免疫法测定实验性胆道炎症兔胆系组织以及几种胆道疾患病人胆系组织中６－ｋｅｔｏ－ＰＧＦ１α与ＴＸＢ２的含量。结果显示：动物模型组与病人组的上述两指标均显著增高；ＡＯＳＣ病人的ＴＸＢ２增高更明显，而胆道梗阻病人胆管组织无此变化。提示前列腺素类及血栓素对胆道炎症的发生可能有关，ＴＸＢ２的负性作用尤为重要。     

植入镍钛记忆合金支架治疗恶性胆道梗阻的临床分析

目的 评价植入镍钛记忆合金支架治疗恶性胆道梗阻的疗效。方法 对16例恶性胆道梗阻患者。采用经手术及介入方法植入镍钛记忆合金胆道支架。结果 术后1个月内死亡1例，15例黄疸完全解除。随访15例，12例术后平均生存13．1个月。结论 植入镍钛合金胆道支架可提高姑息切除的疗效；对不能切除病灶患者，支架植入可解除黄疸，改善生活质量。
